This invention relates to certain newv and l 192e.l I ,semina seam. itsangularly directed portion ybeyond the peuseul-improvements in locks andrefers'more riphery of the mounting head ortopermit particularly to thattype of lock in which the retraction of the locking bolt, frees themounting head fo'r longitudinalmovement,` means being provided forguiding and limiting such movement. 4 l Heretofore, the means forvguiding and limiting the movement of the mounting head had numerousobjections, principal 'of which `was"v the possibility of thescrewbecoming loosl ened and thuspermitting detachment of the mountinghead from lits casing, and the ad-y ditional time required in assemblingand disassembling for purposes or"- repair.

f With these and other objections in mind, this invention has as one oiits objectsthe provision of improved means forrguiding and limiting thelongitudinal movement of the mounting head of locks of the characterdescribed,.which automatically becomes opera-n tivey upon the insertionci the mounting head'4 in its casing.

Another object of this invention resides in the provision of a lockofthe character described in which the means for limiting and guidingthe longitudinal movement of its mounting head is retained in operativeposi# part movement' to the mountln head.

Another object of this invention resides in the provision of a lock ofthe character described having means which, when `in normal position,prevents the outwardy movement of the lock cylinder mounting head with irespect to its casing, and which may be readily moved to inactiveposition to4 permit 'detachment of the mounting head fromits csing bymerely depressing a portion thereo ,A further object of this invention`is to provide' an improved means for limiting the longitudinal movementof a lock cylinder, mounting head with respect toits casing, whichconsists of a plate member having an angular projection with meanscarried by the projection and received in recesses 1n the l mountinghead to maintain the same 'assem (bled with the mounting head and permitrocking movement thereof to either project its movement.v within theperiphery of the-s with. respect to its casing, 'from bendable l metal,4 Y

With the above and other objects in view which will appear as thedescription proceeds,

my. invention resides in the novel construction, combination andarrangement of parts substantially as hereinafter described and moreparticularly defined by the appended claims, it beingunderstood thatsuch chan es 1nthe precise embodiment of the herein isclosed 'inventionma "be made as come within the scope of the c aims.

in the accompanying drawing, I have illustrated one complete example ofthe physical embodiment of myinvention constructed according to the bestmode li have so far devised for the practical application of theprinciples thereof, and in which:

Figure l is a view of a lock device embodying my invention with partsbrokention by theexpansive spring provided to imaway and in section toillustrate structural.

details partly in section, taken through Figure 1 on Y the plane of theline 2 2; Figure 3 is a view similar to Figure 1 illustrating the mannerin which the'means for limiting longitudinal movement may be moved to aninactive position, and 4 Figure 4 is a perspective view .of the lockcylinder mounting head andthe means for .i

limiting longitudinal movement of with respect to the casing.

Referring nogr more particularly to the accompanymg drawing, in whichlike numerals designate like parte throughout the severai. views, thenumeral 5 designates a tubular casing having a sieeve 6 extended fromone and thereof to which the adjacent end of a flexible 'armoured cable7 1s secured.

The /cable 7 contains one or more conductor wires, not shown, whichieedfrom aswitch ico ventional lock structure includin bendable metaland consists o (not shown) `mounted\ in the casing, and having anactuating member 8 movable with a lock cylinder mounting head 9 mountedin the opposite end of the casing 5. The lock cylinder mounting head isyieldably urged outwardly of the casing by an expansive spring 10confined between the inner end of the lock cylinder mounting head and asuit? able stop member 11 within the casing, the mounting head beingrestrained against lon- Pgitudinal fmovement by a locking bolt 12 which,when in locked position, extends beyond the periphery of the mountinghead through a suitable opening 13 formed in the casing wall.

The locking bolt 12 forms part of a cona lock cylinder 14 rotatable inthe mounting head and having the usual tumblers, not shown, which, uponthe insertion of a proper key 15 are movable to an inactive po'sition topermit the rotation of `the cylinder to actuate the locking bolt 12toits unlocked position within the periphery of the mounting head. Thusit will be seen that when the key 15 is inserted and turned toretractthe locking bolt to its unlocked position, the spring 10 moves themounting head outwardly to effeet the desired movement of the switchactuating member 8, the movement of the mounting head being guided andlimited by the stop 16 of a novel stop member 17, and which is movablein an elongated slot 18 formed in the casing wall, said stop engagingthe outer end of the slot when the head 1s in its outermost position, asillustrated in dotted lines in Figure 2.

The stop member is preferabl formed of a plate I9 having its ends shapedto conform to the diameter of the lock cylinder mounting head and havinga member 20 of reduced width extended centrally from its upper edge, atan angle slightly greater than a right angle, the

outer end of said memberforming the stop 16. fvThe stop member ismounted. from the inner end of the cylinder mounting head by y means ofa pair of projections 21 extended from opposite sides of the member 20at a medial point and received in recesses 22 formed in the mountinghead and which communicate with a central recess 23 of equal depth andadapted to receive the member 20.

f The inner end of the moun head is cut away, as at 24, to provide anover anging portion 25 through which the central recess 23 extends to apoint ilush with the cut away portion 24. The intersection of the'vertical portion ofthe recess 23 .which is flush with the cut awayportion 24 and the horizontal portion of the recess is provided with anupwardly projected semi-circular boss 26 which provides a fulcrum aboutIwhich the stp member-is rockable, as will be readily apparent.

WhenY the stop member is assembled with the mounting head in the mannerdescribed and the plate 19 thereof is flush against the cut away portion22,'the end 16 of its member 20, by reason of its angular positionextends beyond the periphery of the mounting head,

as clearly illustrated in Figurel, and due to the interlocln'ng actionbetween the projections 21 and the recesses 22, detachment of the stopmember. from the mounting head may be accomplished only by lifting themem.

periphery of the mounting head and into the slot 18. Continued movementof the mount .ing head aligns the locking bolt with its opening 13,which due to the action of its spring,

not shown, snaps into place and locks the head against longitudinalmovement.

It will be noted that the end 16 of the stop member not only limitsoutward longitudinal movement of the mounting head, but likewisemaintains the same in pro er transverse alignment with the casing toinsure the alignment of the. locking bolt with itsopening 13. r

When it is desired to remove the mounting head for purposes of repair orthe like, it is only necessary to insert a convenient tool throughtheslot 18 and depress the end 16 of the stop member within the peripheryof theI mounting head as Iillustrated in Figure 3, when the tension ofthe spring 10 will quickly move the mounting head outwardly of thecasing. v

From the foregoing description, taken in connection with theaccompanying drawing, ity will be readily apparent to those skilled inthe art to'which an inventonof the character described appertains, thatI provide an improved manner of guiding and limiting the movement of alock cylinder mounting headv within its casing which incorporates meansbecoming active upon the assembly of the mounting hea with its casing,and which is readily movable to aposition uermitting detachment of themounting hea from thel casing'.
